INTRODUCTION;
Gamekeeper’s Thumb is a common but often misunderstood injury affecting the thumb’s stability, especially at the ulnar collateral ligament (UCL) of the thumb’s metacarpophalangeal (MCP) joint. Though the name suggests a sporting background, this condition can affect anyone — from weekend athletes to office workers, parents lifting toddlers, or fitness enthusiasts.
If you’re experiencing pain, weakness, or instability in your thumb, this could be a sign of Gamekeeper’s Thumb — and Physio 360 is here to guide you toward recovery with expert physiotherapy care.
What is Gamekeeper’s Thumb?
Gamekeeper’s Thumb refers to injury or chronic strain of the UCL, the ligament that stabilises the inside of the thumb’s MCP joint. This ligament keeps your thumb steady when gripping, pinching, or holding objects.
Although originally described in Scottish gamekeepers who repeatedly twisted the necks of small game — hence the name — this injury is now most frequently seen in:
Skiers (from falls with a ski pole in hand)
Athletes (ball sports like basketball, football, rugby)
parents or caregivers (lifting toddlers)
workers performing repetitive pinch/grip tasks, gym-goers (weight lifting, pull-ups, grips)
Anatomy & Why It Matters
The Ulnar Collateral Ligament (UCL) runs along the inside border of the thumb’s MCP joint. Its job is to prevent the thumb from bending too far outward (abduction). When this ligament stretches or tears, the thumb becomes unstable — especially when performing pinch grips like holding keys, opening jars, or handling objects.
Symptoms of Gamekeeper’s Thumb
Signs can vary depending on severity:
Mild to Moderate Sprain.
Pain along the inside of the thumb
Swelling at the MCP joint
Weak pinch grip or difficulty holding objects
Discomfort with pushing, pulling or twisting movements
Severe Sprain or Complete Tear
Significant instability in the thumb
Difficulty gripping or pinching
Bruising and tenderness
A feeling that the thumb “gives way”
In chronic cases, reduced hand function
If pain persists longer than 48–72 hours, it’s time to seek professional physiotherapy — early management improves outcomes considerably.
How Gamekeeper’s Thumb Happens
There are two primary mechanisms:
1️⃣ Acute Trauma
This is the most common cause:
A fall onto an outstretched hand with thumb splayed
Collision in sport
Sudden force pushing the thumb backward
2️⃣ Repetitive Strain
Gradual weakening of the UCL from long-term stress:
Repetitive pinch gripping
Manual work with tools
Continuous lifting without proper posture
At Physio 360, we assess your activity patterns to create a personalised treatment plan that is tailored to your needs.
Diagnosis: What to Expect
Most cases of Gamekeeper’s Thumb can be diagnosed through:
✔️ Clinical examination — by assessing thumb stability
✔️ Stress testing — to check ligament laxity
✔️ Imaging (if needed) — X-rays or ultrasound to rule out fractures or significant tears
Prompt assessment prevents chronic instability and pain.
Non-Surgical Treatment with Physio 360
Non-operative care is effective for most mild and moderate UCL injuries, and our goal at Physio 360 is to restore strength, stability, and function safely and quickly.
Here’s how we treat Gamekeeper’s Thumb conservatively:
1. Initial Protection & Pain Control
Thumb splinting/bracing to support healing
Ice therapy to reduce swelling
Activity modification to prevent further strain
2. Manual Therapy Techniques
Our physios use hands-on techniques to:
Reduce stiffness around the thumb and wrist
Improve soft-tissue mobility
Enhance joint movement without pain
3. Progressive Rehabilitation Exercises
A structured exercise plan includes:
✅ Passive range-of-motion exercises
✅ Active range-of-motion exercises
✅ Strengthening drills for the UCL and surrounding muscles
✅ Functional tasks that mirror daily life requirements
Examples include:
Thumb abduction/adduction drills
Pinch and grip strengthening with putty or bands
Coordinated hand movements to regain precision

When Surgery Might Be Needed
In cases of:
🔹 Complete UCL tears
🔹 Significant joint instability
🔹 Avulsion fractures
🔹 Persistent pain and dysfunction despite conservative care
Surgery may be recommended. However, even post-surgical patients benefit enormously from Physio 360 rehabilitative physiotherapy, ensuring a full return to activity.
Recovery Timeline: What to Expect
Phase | Timeframe | Focus |
Acute Phase | 1–2 weeks | Pain control, protection |
Early Rehab | 2–4 weeks | Gentle mobility |
Strengthening | 4–8 weeks | Progressive load |
Return to Activity | 8–12+ weeks | Functional training |
Recovery varies based on severity — but with compliant rehabilitation and guided care at Physio 360, most people regain near-normal function.
Tips to Prevent Future Injuries
Avoid recurrence by:
✔ Improving thumb and hand strength
✔ Using ergonomic tools during work
✔ Avoiding risky thumb positions under load
✔ Learning proper gripping techniques
Physio 360 also offers preventive assessment plans to identify weaknesses and correct them early.
